Abstract

1. Process for separating iodine and its compounds from the carbonylation products acetic acid, acetic anhydride or ethylidene diacetate obtained by subjecting dimethylether, methyl acetate or methanol to carbonylation, characterized in that, in order to reduce the quantity of total iodine contaminating the carbonylation products to less than 20 ppb iodine, the carbonylation products are treated at temperatures of 50 to 200 degrees C with hydrogen in the presence of at least one noble metal selected from group VIII of the Periodic System of the elements, and separated from the noble metal.
